SPECIFICATION forming part of Letters Patent No. 668,728, dated February 26, 1901.

Application filed August 15| 1900. Seria] No. 26,954. (No model.)

To 1f/ZZ whom it may concern:

Beit known thatI, WILLIAM E. CRANDALL, a citizen of the United States, and a resident of the borough of Manhattan, inthe city of New York, State of New York, have invented 4certain new and useful Improvements in Perthe foot or leg rest, whereby the foot or leg rest is raised or lowered to or from a horizontal position as the back is raised or lowered from or to a horizontal or a substantially horizontal position, such connections or means for moving and supporting the leg or foot rest being so designed and arranged as not to interfere with the movement of the body of the perambulator with respect to the reach or runningframe upon whichitisyieldinglysupported, while at the same time the desired movement of the parts shall be easily effected and the parts be securely supported in the desired position.

The invention will be more fully described hereinafter with reference to the accompanying drawings, in which- Figure 1 is a view in perspective of a perambulator to which the invention is applied in a convenient embodiment thereof, and Fig. 2 is a detail view of the locking means employed.

rlhe particular form of the perambulator to which the invention is to be applied is immaterial, although it is preferable that the body should be sprin g-sup ported upon the reach or running-frame. As shown in the drawings, the two parts or members A of the reach or runningframe have secured thereto the front vand rear axles B andB, which .receive the front and rear wheels C and C. The body D, which may be of any suitable or desired shape, is preferably secured to bow-springs,

one of which is shown at E, such springs being secured in turn to the respective meinbers of the reach or running-frame A, so that the body has considerable freedom of movement with respect to the running-frame. The footl or leg rest F is pivoted or hinged to the forward portion of the body D, so that it may be lowered when desired from the substantiallyhorizontal position shown in Fig. l toa generally vertical position. likewise hinged or pivoted to the rear portion of the body D, so that it may be lowered from a substantially vertical position to or toward asubstantiallyhorizontal or inclined position, and is preferably provided at each side with an extension or arm g. To the latter is pivoted,at each side of the perambulator, a rod H, which is extended forwardly and is supported by a link I, which is pivoted to the rod at a point between its ends and may be pivoted upon the corresponding member of the reach or running-frame A at a point between the vertical planes which limit the movement of its other end, so that it supports the rod with a minimum of vertical displacement. To the end of each rod A is pivoted a link K, independent of the link I and connected pivotally with the foot or leg rest F, so that the thrust of the rods H is transmitted direct-ly to the rest F through the links K, the links I serving only to support the rod.

It will be observed that when the back is in the position represented in Fig. l the foot or leg rest will be supported in a substantially horizontal position, as also shown in said figure, an'd that when the bac-k is moved to a substantially vertical position the rods H,

swinging upon and with the supporting-links l, will draw the linksK backward,per1nitting the foot or leg rest to drop to a substantially vertical position. It will be evident, furthermore, that while the foot or leg rest is held firmly against fallin g accidentally, nevertheless, by reason of the support of the rods by the links I, which are preferably inclined about as shown, the oscillations of the body with respect to the running-frame or reach will not be prevented or interferedwith and such oscillation will not be liable to cause an accidental falling of the foot or leg rest. Furthermore, by th'e described arrangement The back G is IOO of rods and links the desired movement. of the foot or leg.Y rest is easily effected the position of the back is adjusted.

For the purpose of locking the back and the foot or leg rest in any desired position an arm L is secured to the back G at a point midway between its sides, such arm being preferably curved somewhat and being also somewhat elastic. The arm L is engaged by a suitable locking or clamping device carried by the body D and is preferably slotted, as at l, to straddle a threaded stud m, which is carried by a bar M of the body and receives a thumb-nut m'. By such means the back can be securely fastened in any desired position, the foot or leg rest being at the same time secured in a corresponding position.

I claim as my invention- A perambulator comprising,r the front and rear wheel-carrying axles, the longitudinallyextending reach members connecting the said axles, a body, springs secured to the reach members and supporting the body thereabove, a swinging foot-rest at the forward end of the body, a swinging back provided with downwardly-projeetin,er lever-arms, longitudinallyextending conneotingrods pivoted at their rear ends to the lower ends of said lever-arms, supporting-links pivoted at their lower ends to the reach members, and at their upper ends pivoted to said connecting-bars near the forward ends thereof, and operating-links pivoted at one end to the forward extremities of the connecting-rods beyond the pivots of said supporting-links, and at their opposite ends pivoted to the foot-rest beyond its pivotal point; substantially as de scribed.

This specilication signed and witnessed this 9th day of August, A. D. 1900.
